Who merges this

Why this pair is hard

German, Russian and Turkish devoice a final consonant, so 'bad' ends like 'bat'. Spanish, French and Italian have an unaspirated dental t, so an initial T can be heard as D. Mandarin, Cantonese and Korean have no voiced stops, so the contrast has to be rebuilt on the hum.
